Doctors have found a dna marker that predicts the inheritance of a deadly disease, als. the band of markers labelled "c" shows the pattern inherited by people with the disease. one member of the green family, the father, has als. his four children have been tested and the results are shown here. to inherit the disease, you must inherit all markers. will any of mr. green's children have the disease? explain.

Doctors have found a DNA marker that predicts the inheritance of a deadly disease, ALS. The band of markers labelled "C" shows the pattern inherited by people with the disease. One member of the Green family, the father, has ALS. His four children have been tested and the results are shown here. To inherit the disease, you must inherit all markers. Will any of Mr. Green's children have the disease? Explain.

Maybe. Child #1 has all but one of the markers for ALS.

No. The markers show that Mr. Green is not the father of the children.

Yes. Child #1 has the markers for the disease.

No. None of the children have all of the markers for ALS.

No, none of the children of Mr Green will have all the markers for ALS.

Option D

ALS or the amyotrophic lateral sclerosis is a neural disease that is mainly of etiological cause, but sometimes it is inherited and then, it can lead to Juvenile Motor Neuron Disease. Here in this disease, the muscles slowly become stiffened and the feedback response is very much delayed from the brain. When inherited, it's an autosomal recessive disease. As it's autosomal recessive disease, both the alleles present of this gene needs to be mutated allele to manifest this disease.

In Mr Green's family, the person has the disease, but there's no history of this disease in the Mother's heredity. So mother is completely normal, and this results the kids to have a heterozygous trait. This therefore makes them the carrier of ALS, not the patients of ALS.

why many students visually perceive stem as a vapid class?

for many students, however, stem subjects are optically discerned as vapid, tedious, and destitute of authentic-world applications. science and math have always been a major part of the high school curriculum, but many students have disengaged from these subjects because they don’t optically discern that they have any pertinence to the authentic world or students’ daily lives. for them, math and science have become a set of rules, procedures, laws, theorems, and formulas to memorize. some students even develop math apprehensiveness and cerebrate they are incapable of learning higher-level mathematics.

why is stem paramount?

as the u.s. economy changes, the ordinant dictation for stem-capable workers is growing. in may of 2014, the u.s. bureau of labor statistics counted more than 8.3 million stem jobs, which accounted for 6.2 percent of total employment in the cumulated states. that number is expected to perpetuate to increment as u.s. companies grow and innovate to compete in the ecumenical economy. according to the u.s. department of labor, the average salary for all stem jobs is $85,570, which is virtually double the average salary for all jobs.

many people still envision stem professionals as wearing a white lab coat and conducting research in a laboratory. in authenticity, some of the most in-demand stem fields are petroleum engineering, process engineering, and computer engineering. these fields that are experiencing shortages of qualified candidates are additionally among the highest paying, with the average petroleum engineer earning an annual salary of $147,520 in may 2014 according to the u.s. bureau of labor statistics.

in additament, stem subjects edify students valuable skills that are vital for prosperity in all vocations, even those that do not directly require stem erudition. engagement in stem subjects avails students develop quandary-solving, critical mentally conceiving, and leadership skills. these skills are so ecumenical, in fact, that statistics relinquished in the summer of 2013 by the u.s. census bureau designated that about three-quarters of the people with a bachelor’s degree in stem fields are not working in those vocations. many non-stem employers are poaching stem-qualified job candidates because they are more ingenious and collaborative than their non-stem counterparts.

as the ecumenical economy perpetuates to evolve, the desideratum for stem-capable workers will perpetuate to grow. by getting edifiers and students involved in the stem kineticism, an incipient generation of adroit workers will be poised to energize and expand this exhilarating field.
